The invention relates to steam pipe connections for steam-heated pressing irons.

An object of the present invention is to improve the construction of steam pipes for feeding steam to and exhausting steam from a steamheated pressing iron and to provide simple and comparatively inexpensive steam pipe connections adapted to permit easy movement of a pressing iron longitudinally and transversely of an ironing board or table as well as movement in a circular or elliptical path and also adapted to be moved upwardly and downwardly to enable the raising and lowering of the pressing iron to place the same on the work and to lift it therefrom without any tendency of the iron to bind or stall because of the steam pipe connections.

A further object of the invention is to provide for a pressing iron mounted for the said movements, steam pipe connections forming'opposite linkages located at opposite sides of the iron supporting and guiding means and adapted to balance each other and thereby relieve the pressing iron of any tendency to sag or twist because of its connection to the steam pipes for supplying steam to and exhausting steam from the pressing llOl'l.

With these and other objects in view, the invention consists in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, and minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Referring particularly to the form of the invention illustrated in Figs. 1 and 2 of the drawings, I designates a steam-heated pressing iron connected by the steam pipe connections hereinafter described to steam supply and exhaust pipes 2 and 3 and mounted for the various necessary movements over an ironing table t by any suitable means which will permit an upward and downward movement of the pressing iron, backward and forward movements longitudinally of the ironing table 4, lateral movements across the table, and circular and elliptical movements as well as a pivotal movement on a vertical axis to enable all of the various movements required for ironing to be made by manual manipulation of the pressing iron. The means for mounting the iron to permit such movement comprises a stationary bearing bracket 5 suitably secured to the ironing table t at the inner longitudinal edge thereof and provided with spaced bearing eyes it, through which passes a horizontal pivot or pintle l which pivots or hinges a movable bearing bracket 8 to the stationary bearing bracket 5. The stationary bearing bracket 5 is preferably provided with a recess 9 to receive the adjacent edges of the table l and the movable bearing bracket 8 which extends upwardly from the stationary bearing bracket has at its lower end a bearing eye ii for the reception of the said pintle l. The bearing eye 6 of the movable bracket is located between the spaced eyes Iii of the stationary bearing bracket and the pivot 1 passes through the eyes 6 and iii and forms a pivotal connection for the movable bracket. This permits the movable bearing bracket 8 to swing on a horizontal axis.

The movable bearing bracket is provided above the table with spaced vertically aligned bearing eyes H, through which passes a vertical pivot or pintle l2 which hinges or pivots an arm iii to the movable bearing bracket and permits the arm 13 to swing horizontally. The arm 13 which extends upwardly and forwardly from the hinged bearing bracket '8 is provided at its upper end with a horizontal guide i i. The guide I l receives a slidable bar 15 which carries at its front end the pressing iron I andwhich is provided at its front end with a head it having an opening it in which is mounted a vertical pivot it. The pressing iron is connected with the lower end of the pivot It by a suitable hinge connection is which permits the pressing iron to maintain its lower pressing surface in a horizontal position when the pressing iron is lowered from the elevated position illustrated in Fig. 1 to the ironing table 4. The pivot 1 at the lower end of the bracket 8, the hinged connection (9 at the lower end of the pivot 18, and the hinged connections between the front and rear steam pipe connections, permit the pressing iron to pivot about the hinged connection IS. The pressing iron I, which is provided with a suitable operating handle 20, may be of any desired construction and is hollow for the reception of the desired amount of steam which is fed into the iron and exhausted therefrom by means of the steam pipe connections which connect the pressing iron with the steam supply and exhaust pipes 2 and 3.

A rear upright steam pipe section 2! is connected by a standard swivel pipe joint 22 with an elbow coupling 23 of the steam supply pipe 2, and the said rear upright steam pipe section 2| is connected by a hinge joint construction 24 with a rear horizontal steam pipe section 25. The rear horizontal steam pipe section 25 extends forwardly from the rear upright pipe section and is connected by a hinge joint connection 25 with the rear end of a front horizontal steam pipe section 27, and the front end of the latter is connected by a hinge joint construction 28 with the pressing iron in advance of its center, at which point the vertical pivot 68 is preferably located.

The exhaust pipe 3 which is provided with a elbow coupling 29 is connected by a standard swivel joint 30 with a rear upright pipe section 3| arranged similar to the rear upright pipe section 2! and connected by a hinge joint structure 32 with the rear end of a rear horizontal pipe section'SS. The front end of the horizontal L pipe section 33 is connected by a vertical hinge joint construction 34 with the rear end of a front horizontal steam pipe section 35 and the latter is connected at its front end with the steam pressing iron at a point in rear of the center of the pressing iron by a vertical hinge joint construction 36.

All of the hinge or swing joint constructions for connecting the front and rear horizontal pipe sections with each other and with the rear upright pipe sections and also with the pressing iron are of similar construction, preferably as illustrated in Fig. 3 of the drawings. Each hinge or swing joint construction comprises a tubular member or pipe section 31 and a coupling rnember 38 carrying a collar or cap 39 which receives a coiled spring Ml. The tubular member 31 has a tapered portion ll which fits in a tapered portion 42 of the opening E3 of the coupling member.

This tubular member 3? also has a reduced cylindrical tubular extension 31 resulting in a shoulder 45. This extension 3'? has a tight rotatable connection with the wall of the cylindrical portion =43 of the coupling member and which provides for an effective means to prevent wobbling of the tubular member 31 and to prevent accidental leakage of steam and obviating unnecessary wear of the tubular member in its movements in the coupling member.

The coiled spring All is arranged on the cylinand a packless steam tight joint or connection is maintained between the tubular member and the coupling member, providing metal joint connecting sections of metal pipes through which liquids, gas, steam or fluids pass at high pressures, providing joints that dispense with packing.

The collar or cap 39 is interiorly threaded to screw onto the threaded portion 46 of the coupling member and it has an opening 4'! through which the tubular member 3'! passes. The spring is housed within the cap which is provided with a set screw 48 for engaging the coupling member to prevent the cap from being accidentally unscrewed by the relative rotary movement of the hinge or swing joint.

The adjustment of the collar or cap on the threaded portion -46 of the coupling member provides for tensioning of the spring to maintain the steamtight joint or connection between the tubular member 31 and the coupling member 38. The coupling member 38 is provided with intermediate polygonal wrench receiving portion 49 and also has a threaded terminal portion 53 to receive a nipple or coupling 5! for connecting it to the adjacent pipe section.

The hinge or swing joint constructions permit the front and rear horizontal members 25 and 21 and 33 and 35 to yield to the various movements of the pressing iron. The rear pipe sections 25 and 33 diverge forwardly from the rear upright pipe sections and the front horizontal pipe sections 2? and 35 diverge rearwardly from the pressing iron to their point of connection to the rear horizontal pipe sections. This arrangement, while permitting free movement of the pressing iron without the steam pipe connections causing any binding of the parts, also provides a linkage at opposite sides of the means for mounting the pressing iron, and the linkages balance each other and eliminate any tendency of the steam pipe connections tending to cause the pressing iron to tilt. I I 1 Any suitablemeans having an operating handle 52 may be provided for controlling the flow of steam into the pressing iron and the exhaust of steam therefrom, and, as such feature does not constitute a, portion of the present invention, further description and detailed illustration thereof are deemed unnecessary. The standard swivel pipe joints 22 and 35 are horizontally disposed and are located at opposite sides of the lower hinge connection of the movable bracket 8, coincident with the axis formed by the pivot or pintle 1, so that the steam pipe connections are adapted to swing on the same horizontal axis as the means for mounting the pressing iron and for permitting raising and lowering of the same.

In the form of the invention illustrated in Figs. 4 to 6, inclusive,- tiie steam pipe connections for connecting steam supply and exhaust pipes 53 and 54, with the exception that the said steam pipes are located at one side of the means for mounting the pressing iron, are similar in construction.

The means for mounting the slidable bar H which carries the pressing iron are substantially the same as the means heretofore described and like numerals or designations are applied to the corresponding parts of such mounting, and detailed descriptions thereof in connection with the form of the invention illustrated in Figs. 4 to 6, inclusive, are therefore unnecessary. The steam pipe connections comprise rear upright sections 55 and 56 and rear horizontal steam'pipe sections 5'l and 58 and front horizontal steam pipe sections 59 and 60, which are connected together and with the rear upright pipe sections and with the pressing iron 6! by hinge joint constructions of the same construction as that heretofore described. The horizontal front and rear steam pipe sections 51 and 58 and 59 and 60 are located one above the other and at one side of the means for mounting the pressing iron and the front horizontal pipe sections are connected with the pressing iron at 62 and 63 at transversely spaced points, as clearly illustrated in Fig. 5 of the drawings.

The front horizontal steam pipe sections 59 and 69 are preferably composed of telescoping members 64 and 65 which are slidable with respect to each other, as clearly illustrated in Fig. 6 of the drawings. This construction cooperates with the hinge joint structures in permitting free movement of the pressing iron over the ironing table. Any suita le packing means 65, as illustrated in Fig. 6 of the drawings, may be employed for providing a steam-tight connection between the telescoping members of the front horizontal pipe sections. While in the description of the several forms of the invention the steam supply and exhaust pipes 2 and 3 and 53 and 5 3 are referred to, either on of these pairs of pipes may be employed as a steam supply pipe and the other as a steam exhaust pipe, as will be readily understood.
